Foam bladder tank, together with ratio controllers, form a balanced pressure
proportioning system used to mix water and fire fighting foam together to
generate an effective extinguishing medium.
The bladder tank technology is a mixing method allows the water/foam ratio to
remainstable by automatically adjusting to the variable flow rates and pressure
conditions that may occur during system operation.
This feature makes bladder tanks particularly suitable for multiple hazard
systems, sprinkler systems and any other system operating under variable,
non predictable, flow and pressure conditions.
The bladder tank is a carbon steel pressure vessel containing an elastomeric
separation bladder between the water and foam concentrate. The bladder
permits water pressure to be transferred to the foam concentrate without the
two fluids mixing together. A ratio controller generates a water pressure drop by
means of a reduced cross section where the water stream passes through it.
As the foam concentrate pressure is higher than the pressure at the ratio
controller, the foam starts flowing towards the water and mixing at a calibrated
rate, which is dependant on the water flow rate.
